What Is Optimized Battery Charging on Mac, and Should You Turn It Off?
Optimized Battery Charging learns your routine and holds your MacBook at 80% until it expects you to unplug. Leave it on, unless a charge limit suits you better.
According to Apple, Optimized Battery Charging uses on-device machine learning to delay charging past 80% when it predicts your Mac will stay on power for a long time.
If your MacBook’s battery menu has ever said Charging On Hold while it was plugged in, that was Optimized Battery Charging at work. Here is what it does, when it helps, and what to use instead if it doesn’t fit the way you work.
What Optimized Battery Charging does
According to Apple’s support page About Optimized Battery Charging and Charge Limit on Mac, the feature reduces the time your Mac spends fully charged. It uses on-device machine learning to learn your daily charging routine, and when it predicts your Mac will stay on power for a long time, it waits to charge past 80%. It aims to finish the charge by the time it expects you to need it.
- It needs macOS Big Sur 11 or later and a Mac laptop.
- While it is holding, the battery menu shows Charging On Hold.
- Need it full now? Choose Charge to Full Now in the battery menu.
How to turn it off (or on)
- From the Apple menu, choose System Settings, then click Battery.
- Click the info button next to Charging (or Battery Health, on older versions).
- Turn Optimized Battery Charging off or on, then click Done. When you turn it off, you can choose to turn it off only until tomorrow.
Charge Limit, the newer setting
macOS Tahoe 26.4 added Charge Limit on Macs with Apple silicon. In the same Charging window you can set a limit from 80% to 100%. Your Mac charges to within a few points of it and shows “Charged to [%] Limit”; if the charge drops more than 5% while on power, it charges back up. Apple notes that with either feature your Mac will still occasionally charge to 100% to keep its battery percentage accurate.
Should you turn it off?
| Your routine | Good fit |
|---|---|
| Regular days, unplugged at about the same time | Optimized Battery Charging: it learns the pattern. |
| Always on the desk, irregular hours | A charge limit: it holds 80% no matter what, where Optimized Charging may not predict your day. |
| You need 100% at short notice | Either, with Charge to Full Now when you need it. |
| You use a charge limiter app | Usually turn Optimized Charging off, so the two don’t get in each other’s way. |
The weak spot of Optimized Battery Charging is that it is a prediction. If your days have no pattern, it may simply charge to 100% and sit there. A charge limit doesn’t guess.
Going further: Chargeberry
Chargeberry is a charge limiter for MacBooks with Apple silicon. It holds the limit you choose every time, and adds what macOS doesn’t:
- Limits below 80%. Any limit from 50 to 100% on macOS 14 to 26, with Desk (60%), Daily (80%) and Travel (100%) presets. On macOS 27, Apple locked the charging controls, so there Chargeberry sets macOS’s own limit, 80 to 100%.
- Heat protection. It pauses charging when the battery reaches the temperature you choose.
- Full by a time. Hold 80% overnight and be full at 8:30 every weekday, charging as late as is safe.
- It tells you about conflicts. If Optimized Battery Charging or another battery app could fight its limit, Chargeberry says so.
For a plain 80% cap on macOS 26.4 or later, Apple’s own Charge Limit may be all you need. Chargeberry is $5.99 once, for macOS 14 or later.
Chargeberry
A kinder way to charge your MacBook. $5.99 once, macOS 14 Sonoma or later.

Why does my MacBook say Charging On Hold?
Optimized Battery Charging is holding the battery at 80% because it expects your Mac to stay plugged in for a while. Choose Charge to Full Now in the battery menu to charge to 100% right away.
Is Optimized Battery Charging good for my MacBook?
Yes, for most people. It reduces the time the battery spends full, which slows its aging. It works best if you unplug at about the same times each day.
What is the difference between Optimized Battery Charging and Charge Limit?
Optimized Battery Charging predicts when you’ll unplug and delays the last 20%. Charge Limit, on macOS Tahoe 26.4 or later with Apple silicon, holds a fixed limit from 80 to 100% all the time.
Should I turn off Optimized Battery Charging if I use a charge limiter?
Usually yes. Two features deciding when to charge can get in each other’s way. Chargeberry tells you when Optimized Battery Charging is on.
Why does my Mac still charge to 100% sometimes?
Apple says Macs occasionally charge to 100% with Optimized Battery Charging or Charge Limit on, to keep the battery percentage estimate accurate.
